P-18-2 SURVEILLANCE RADARS
Radar Upgrade (Version 2)
Purpose The P-18 radar modernisation programme is proposed to repl ac e vacuum-tube components with solid-state technology and improve the radar performance.
Composition
• trans mitter control display and automatic frequenc y control am plifier; • automatic radar data reading and recording equipment; • receiver and coherent local oscillato r.
Equipme nt to be modernised includes: • active ja m ming suppres sion equipment; • digital passive int er fer e nce su ppr es sio n equipment;
